To all whom ltmc/y concern:

Beit known that I ELMER W. CoKELr, a citizen of the Unitedtates, residin at Coalin a, in the county of Fresno an State of Ca ornia, have invented a new and useful Friction-Hoist Gear, of which the following is a s ecification in such full and clear terms as enable those skilled in the art to construct and use the same.

This invention relates to reels used for the purpose of taking the sand and broken rock out of the bottom of an oil, gas, or Water Well after the drilling has proceeded to such a point as to make the cleaning of the well necessary.

An object of the invention is to produce a reel that Will be provided with supports that will move sufficiently to throw the weight of the reel far enough o' the center of support to canse it to hug the Winding drum c osely and to cause the brake to hold the drum equally Well.

A further object of the invention is to make a hoist which will have its levers Well out of the way of the person using -the hoist.

A further ob'ect of the invention is to provide a means or holding the friction dru'm shaft in such a manner as to allow its shaft considerable play since when it is moved forward or back cach side may not move precisely the same amount.

A further object of the invention is to provide means whereb the reel will automaticall lock itself W en thrown against the friction wheel or against the back brake, as the case may be.

In the drawings, ill-which the same numerals are ap lied to like parts throughout, Figure 1 is a nt elevation of a art of an oil rig showing this friction hoist, ig. 2 is a side elevation of the same art of an oil rig showing the friction hoist i 3 is a view of one means for allow'in t e rum to have a slight pla Fig. 4 is a p an of the same device shown in ig. 3, Fig. 5 is an edge elevation of the swinging link which supports the drum, Fig. 6 is a front view of said link, Fig. 7 is a view of the platform at the drillers station, Fig. 8 is a side elevation of one half ofthe preferred form-of the drum box and its support, Fig. 9 is a plan of the drum box support, and Fig. 10 is a side elevation of' one orm of the ower portion of the drum box and its support.

The numeral 1 represents the bottom sill of the oil rig frame, and 2 is the side sill of the same only such parts of the rig being shown as are material to the present invention. The frame is provided with the perpendicular brake post 3 and the band wheel post 4 said band Wheel post being set in a mortise in the sill 2 and held in place therein by the block 5. The band wheel 6 is sup orted by the post 4 on the top thereof said wheel being of large diameter and'driven from any suitable source of ower.

Carried by t e sills of the machine are four su porting arches 7 which are bolted to the sil s. These arches are provided on their upper edges with a series of curved depressions 8, shown in Fig. 2, and which are placed at about the center of the oints of contact of the friction drum 9 Wit the band wheel 6 and the brake post 3. The arches are also rovided with a cover plate 1() which is olted to them.

The sand reel drum 11 is carried by the shaft 12 which also carries the friction drum 9. This shaft is supported in. a pair of boxes 13 which each have a depending ear 14, said ear gassin between ears of the supporting bloc s 15, olts passing through the ears and the supporting blocks 15 to hold the boxes in their laces. This supporting block has holes Yt rough it at right an'glesto each other as shown in Figs. 8 and 9, the purpose of said holes beinglto allow one bolt to pass through to secure t e box in its place in such a manner that it may rook.4 The hole shown in Fig. 9 is for the purpose of allowing the bolt 16 to pass through to secure the block to the swinglng link and to allow the block to tum in a orlzontal plane.

The supporting link 17 is carried by the hanger 18 which 1n turn is supported by the arches 7, the pivots 19 being placed in the curved depressions 8 of the arches 7. Attached to the su pporting link 17 is the rod 20 which runs u hig enough to give the roper levera e, an which -is connected to t c rod 21, sald rod 21 being su ported by the bracket 22 and rod 23, the racket 22 being bolted to the post 4 and the rod 23 extending down far enough to be below the top of the sill 2 to a long rod 24 which runs to the latform of the person operating the ri his rod 24 is connected to the lever 25 Whic 1 is operated by the hand lever 26 on the platfor'm 27 by t e engineers side.

Now it will be clear that it is not necessary to ha've the left hand end of the shaft supported by the same kind of a link as the end next the friction drum it only being necessary to have it loose enough to allow the necessa play at the friction drum end to allow the rum to make the requisite movements to touch the brake post and the band wheel, which in practice are but a short distance a art more than the actual length of the ciiord of the friction drum 9.

It will be observed that the total Welght of the friction drum with its coils of ropeA or cable is in the neighborhood of from' 3000 to 4000 pounds so that when it -1s pulled to the osition shown 1n Fig. 2 it kicks the han er back out of the per endicular indicated y the dotted line and t 's makes the drum hug the band wheel that much closer since to move it back to contact with the brake post it must be pushed from above and pass over the center of support of the han er 18 when the hanger will at once kick bac in the opposite direction and make it lock itself in that position.

The drum 9 bears a ainst the face of'the band wheel 6, which is a ged with any sultable materials that ma e at hand and the post 3 may or may not e lagged at the place of contact with the friction rum, but 1n any event the lagging or the face of the post Wears away as the drilling of the well proceeds and it frequentl' becomes necessary to change the position o the hanger 18 to make it swing the friction drum with its load of 'rope properly against the band wheel and the brake post 3. a

From the above descri tion it is thought that the operation of the oist will be clear, it bein understood that the band wheel is used W en it is desired to hoist the rope with its load of tools and mud and the brake when it is desired to stop the drum, the time being so short between the movement of the drum from the brake to the post, or vice versa, as

to prevent the undesired unwinding of ther ro e on the drumll. A

lit will be clear that the single ear 14 of the bearing boxes 13 may be made into two as shown 1n Fi 10, if desired, in which case the part secure to the swinging link 17 will be sim ly a block 15 with two holes therein and the Llower part of the bearing box will have two ears instead of one, the effect being a reversal of the construction shown in the other figures.

What I claim as my invention and desire to secure b Letters Patent of the United States is as ollows:

1. In a friction hoist, the combination with a friction drum of means to move the drum forward and back, a friction wheel, a brake ost on the o posite side of the drum from t e friction W eel, a swingin hanger and a movable link supporting the um and carried by the swin g han r.

In a friction 01st, t e combination with a friction drum of means to move the forward and back, a friction wheel ilf front of the drum, a brake post in the rear thereof and on the opposite side of the drurn from the friction wheel, a lever to move the drum, a' movable hanger for the end of the friction drum ad'acent the lever which moves it back and orth, a movable link supporting the drum and carried b the hanger, and connections coperating with said lever whereby said drum may be moved from a distance.

3. In a friction hoist, the combination of a friction drum, a friction wheel adjacent the drum, a brake post on the o poslte side of the drum from the friction wheel, means to move the drum from a distance, a pivoted hanger, and a link carried by the hanger for supporting the friction drum whereby 1t may be moved into and out of contact with the brake r1plost and friction wheel.

4. e combination of a friction drum, a friction wheel adjacent the drum, a brake post adjacent the drum and on the opposite side thereof from the friction wheel, a swinging hanger for the drum and comprising a connected pair of links having o positely extending pivots at their upper ends and a connecting pin at their lower ends, and means to move the drum toward and away from the brake ost and the friction wheel. i v
